Convert \(330^\circ\) into radians.
B. \( \frac{11\pi}{6} \) रेडियन\( \frac{11\pi}{6} \) radians
\(330^\circ=\frac{330\pi}{180}=\frac{11\pi}{6}\) है। \(30^\circ\) के गुणजों में हर अक्सर (6) आता है। / \(330^\circ=\frac{330\pi}{180}=\frac{11\pi}{6}\). Multiples of \(30^\circ\) often give denominator (6).

What type of angles can \(0^\circ\) and \(360^\circ\) be considered?
C. सहसमापी कोणCoterminal angles
\(0^\circ\) और \(360^\circ\) की अंतिम भुजा समान होती है इसलिए वे सहसमापी हैं। \(360^\circ\) के अंतर को पहचानें। / \(0^\circ\) and \(360^\circ\) have the same terminal side so they are coterminal. Look for a difference of \(360^\circ\).

Which is a positive coterminal angle of \(45^\circ\)?
C. \(405^\circ\)
\(45^\circ+360^\circ=405^\circ\) इसलिए यह सहसमापी कोण है। सहसमापी कोण के लिए \(360^\circ\) जोड़ें या घटाएं। / \(45^\circ+360^\circ=405^\circ\) so it is coterminal. Add or subtract \(360^\circ\) for coterminal angles.

Which is a negative coterminal angle of \(120^\circ\)?
B. \(-240^\circ\)
\(120^\circ-360^\circ=-240^\circ\) होता है। ऋणात्मक सहसमापी कोण पाने के लिए \(360^\circ\) घटाएं। / \(120^\circ-360^\circ=-240^\circ\). Subtract \(360^\circ\) to get a negative coterminal angle.
